This photo essay is based on my visit to Devonish Island in September of 2025. This is an important location for members of the McCauley clan who can trace their lineage through the McQuire clans who resided in this area.

Devenish Island’s monastic site is believed to have been founded in the 6th century by Saint Molaise, a significant figure in early Irish Christianity. Like many monastic settlements of its time, Devenish was established in a remote location, ideal for prayer, study, and reflection. Islands such as Devenish provided both seclusion from worldly distractions and natural protection from potential invaders.

Saint Molaise, also known as Laisrén or Laserian, was an influential religious leader who played a key role in shaping monastic traditions in Ireland. According to tradition, he spent time on Devenish Island, where he established a thriving community of monks dedicated to scripture, scholarship, and religious devotion.

The Augustinian Church, built in the 15th century, is one of the later additions to Devenish Island. This larger and more refined church reflects the ongoing importance of the site in medieval Ireland. Unlike the earlier, simpler monastic buildings, this church features pointed arch windows, a finely carved doorway, and remnants of Gothic-style architecture.

The presence of an Augustinian church suggests that Devenish evolved from its early Celtic Christian roots into a site influenced by broader European religious orders. The Augustinians, known for their scholarly contributions, likely continued Devenish’s tradition of education and religious devotion.

Here are highlights based on the Islands iconic features.
